Microsoft Surface Book has HID multitouch connected device. Enable it here.
The change has been tested on bare metal by reading raw data from
/dev/input/event4.
The patch uses HID device ID submitted earlier here:

I am a little bit lost here. In your previous patch, you unset the group
MULTITOUCH to the USB_DEVICE_ID_MS_SURFACE_BOOK. But here, you bind a
device to it which will never been present according to
http://marc.info/?l=linux-input&m=146280544721389&w=2
Also, please make sure all features are working on the keyboard (special
functions/LEDs).
The good news is I have been sent a Surface 3 with the typecover. So I
intend to work on either fixing hid-multitouch or enabling multitouch
for hid-microsoft depending on which makes more sense.
Cheers,
Benjamin

Yes, that line is redundant. So, the first hunk of that patch should be
removed.

Caps Lock LED is not functional. I have no idea yet what drives it.

Okay, it seems I have to resend these two as one without mentioned hunk.
